Opt for the big 6.2-liter V8 and the right configuration and you’ll get a class-leading 12,500-pound tow rating. The Toyota Tundra can’t match the Sierra’s horsepower and doesn’t offer upscale features like ventilated front seats or adaptive suspension.
If you’re seeking a diesel or turbocharged engine in your next half-ton pickup, the 2018 GMC Sierra is off the list. You can get a diesel in the smaller GMC Canyon, a less expensive option that nearly matches some of the Sierra’s bed and payload figures.
